Easy to use but do not last as long as 1.45 volt batteries
on November 24, 2013
These batteries made in Germany are easy to use, but they do not work for a long time. I thought that my hearing aid was broken, but my ear doctor said the problem is that they are 1.4 volt batteries, and I should buy 1.45 volt batteries which last longer.
